That's true, so just so I'm understanding it correctly a quick recap, thinking of the whole thing as a function in p^{0}: We've got an expression which is a sum over poles in p^{0} - with positions determined by the energies E_{\textbf{p}} corresponding to given states...

Hey p-brane, thanks for the reply. So implicit in the first steps you make there is that at the pole region only: p^{0} \rightarrow E_{\textbf{p}} Basically you can argue 'backwards' and reinterpret E_{\textbf{p}}p^{0} where instead: E_{\textbf{p}} \rightarrow p_{0} ...

Hi folks, Been trying to fill some of the more formal gaps in my knowledge by tackling the more technical stuff in P&S Chapter 7. Their derivation of the LSZ formula is quite different to those of books like, say, Srednicki, as they basically Fourier transform the whole argument as I...
